JOHN MORROV AND FRANK CURTIS, JR., OF INGERSOLL, ONTARIO, CANADA SELF-HEATING SAD-IRON.

SPECIFICATION :forming part of Letters Patent No. 428,403, dated 'May 20, 1890.

Sen'al No. 326,642. (No model.)

To @ZZ whom t may concern;

Be it known that we, JOHN MORROW and FRANK CURTIS, Jr., subjects of the Queen of Great Britain, residing at Ingersoll, Province of Ontario, Canada, have invented certain new and useful Improvements in Self-Heatin g Sad- Irons, of which the followingis a specification, reference being had therein to the accompanying drawings.

Our invention has relation to a self-heating smoothing and sad iron, and more particularly to that class which employs a reservoir or other means which furnishes the hydrocarbon liquid from which vapor is generated and ignited in the body of the iron, thereby heating the same; and it has for its object, among others, to provide an improved burner for such devices by means of which the iron Inay be quickly heated, the parts of the burner being readily assembled or taken apart for cleaning or other purposes, and capable of Inanufacture at a Ininimumcost.

Other objects and advantages of the invention will appear in the following description,

and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a side elevation, partly in longitudinal vertical section, (the reservoir being partly broken away to expose the interior construction,) of

,an iron constructed in accordance with our invention; and Fig. 2 is a detail, hereinafter referred to.

Like characters refer to like parts in both the figures of the drawings.

A is the iron proper, which is hollow and provided with a suitable cover or lid A', openings A2 being left at the sides to admit air to aid in the combustion of gas formed therein. As are perforations formed near the base of the iron for the same purpose.

The handle A4 and bail A are of any ordinary well-known construction, and the bail is secured to the lid or cover A by means of the screw (or screws) A5. Formed on the interior of the iron and on the base thereof are the risers A, on which the burner B is adapted to rest..

The burner B is provided with a series of perforations along its under surface, as at B3, and with a branch B', which projects beyond the end wall of the iron, as at BX, and has formed on or near its end the upwardly-extending lug B2. The burner and lug maybe cast integrally with the main portion of the iron, or may be seated in or form a portion of the end wall of the iron, as clearly indicated in Fig. 2.

`The lug is adapted by screw-threading or otherwise for the reception of the conduit or tube C, which is screw-threaded to Iit the same, and on its interior surface is roughened and preferably and most easily in the form of a coarse spiral thread CX. Cylindrical corrugations may be elnployed,but corrugations with a thread-like pitch are preferable.

C is an interiorly-serew-threaded sleeve,

one end of which is adapted to receive the ing an opening ator near its center for the pin E of the indicator et., the lower end of the pin being bent, as at E', to prevent its separation from the strap.

The function of the indicator, which is of buoyant material, is to show when the reservoir is filled, so that it will be only necessary to remove the cap,when the result will be apparent.

F is a valve (shown in dotted lines in Fig. l) which controls the supply of oil from the reservoir into and through the tube C, and may or may not be used, as desired.

G is a jet-orice tube which controls the supply of gas and liquid which flows into the burner of the iron, and is screw-threaded into t-he lug B2 of the branch B of the burner B. The j et-orifice tube G is provided with a bore G', which registers with the opening formed in the tube C, an opening G2 being formed at its elbow to admit of access for cleaning purposes, being closed by a screw G2X. G2 is a needle-valve, which closes the opening of the jet-orifice tube G and controls the supply of gas flowing therethrough.

The operation of the invention is as follows:

IOO

` duces the heat and continues the vaporization Ifo reservoir is full.

and combustion.4 The interior roughening or corrugation CX of the tube C while it does not materially obstruct the flow of oil therein retards it sufficiently to accomplish a more speedy and satisfactory vaporization of the fuel. We place a cap G4 on the point of the jet-orifice tube G, so that should the hole which emits the gas become clogged by any means the cap may be readily removed and the hole cleaned while the iron is hot and the The seat of the needle-valve G3 is in the j et-orifice tube G.

Having described our invention and its operation, what we claim is- 1. In a self-heating sad-iron, a body A, formed upon its interior at the base, with risers A6,combined with the burner resting upon said risers and having a branch B projecting through the end wall of said body, a feed-tube supported in the wall of the body and centrally above the burner, a reservoir connected with the feed-tube, and the connection between the tube and the branch B of the burner, substantially as described.

2. In a self-heatingsad-iron, a hollow burner provided on its under surface with perforations and at one end with an outwardly-proj ectin g bran ch having a lug, combined with a feed-tube arranged centrally above said burner, a jet-orifice tube connected with said lug and having a passage arranged at an angle to the feed-tube and parallel with the branch, and having a needle-valve in line with said branch, substantially as described.

3. The combination, with the burner having the branch B and the lug B2, of the feedtube engaged with said lug, the j et-orifice tube, also connected With said lug and having a valve-controlled passage in line with the branch of the burner, with a detachable perforated cap upon the portion of the jet-tube adjacent to the branch, substantially as described.

4. In a sad-iron, the combination, with the reservoir, of the valve-tube or jet-orifice tube provided with an openin g adapted to be closed by a needle-valve, a needle-valve, and a removable cap closing the opening and having a passage therethrough, substantially as and for the purpose speciied.

5. In a sad-iron, the combination, with the burner having upturned branch B', a lug B2, of the jet-orifice tube connected with the lug, with a passage substantially parallel with the branch, a passage at right angles thereto, and a passage in line with the branchand coutrolled by aneedle-valve and having its discharge into said branch, with a space between the discharge end and the adjacent end of the branch, and a movable cap closing the opening and having a passage therethrough', substantiallyT as shown and described.

In testimony whereof We affix our signatures in presence of two witnesses.
